1– CTRL + Mousing over and item on the ground (outside of inventory) shows stats so you aren’t forced it up. (kallell)Doing this while having your inventory open should compare the item on the ground to what you currently are wearing as well. (broken1000)

2- There is a “force move” (labeled “Move” and is unbound by default) button that is unbound by default. This is helpful for running through packs of monsters and not accidentally clicking and attacking one. (need to manually bind) (kallell)

3- You can link items by bringing up the chat text box and shift+clicking an item, making it easier to show items to people to see if they need them or if you're in different areas. (twincannon)

4- If you think you have an upgrade for someone you're playing with, instead of asking him you can inspect him by right clicking his icon on the top-left. (twincannon)

5- Whites/grays sell for next to nothing and really aren't worth the inventory space outside of the first act, just toss that junk for less town trips (make sure to check the prices in nightmare mode and beyond though, who knows if this will change later on). (twincannon)

6- Buy +2-4 damage magic rings ASAP, they're pretty overpowered when they become equippable at levelRestart the game a few times if they don't show up, or if they give a poor secondary bonus. (twincannon). Buy @ Radek the Fence: http://i.imgur.com/C0VXGh.jpg (Sf4tt)

7- Never sell magic items to a vendor as the crafting mats will probably sell for more in most cases (will change in retail but in beta, magic stuff sold for 50-75 usually and the essence sold for 150). Also rumors that you can trade the essence upwards, i.e. 10 normal mode essence for 1 nightmare mode one. (twincannon)

9- If leveling up with a friend, designate one of you for leveling up the jeweler artisan (JC is MUCH cheaper) and one for blacksmith artisan, saving half the money required. (twincannon)

Although I don't remember the exact numbers, the Blacksmith will require about ~700,000 gold to level up to max, while the jeweler will only take about ~45,000. (tolvinar)

10- You can hold left click to run around and simply tap shift to "stutter walk" fire instead of clicking the mouse (holding shift and casting will make you cast the ability in place,), works well for ranged characters to give your clicking finger a bit of a break. (twincannon)

11- If you've got a big friends list and don't want people to join your game without your permission, or just want to play alone, there's an option to disallow "Quick Join" under social options which is what makes your game show up with a "Join" button for friends (twincannon)

12- If you open your inventory (C or I), and THEN hold ctrl while mousing over the ground loot, it will pop out the compare box instead of just the item's own stat box. (similar to when mousing over an item in your inventory -- shows dps changes, etc.) (exuled)

13- And if you hold ALT it will compare to your off-hand/equip to your off-hand, while in inventory of course. Handy for dual-wielders. Also works on rings. (Nyctalgia)

14- You need to activate lecterns yourself. It is different than a chest as only you can activate your lecterns. If they don't drop lore they can still drop gold. (rec916)

15- When you are leaving a game and the timer is counting down because you are not in town, your mouse does not work but your keyboard does. You may be frozen and getting beat up while waiting to leave the game but you can still fire off those skills with 1-4. (rec916)

16- Lore books give EXP, make sure to pick up all you can. (Only works on lore books you have not already picked up!) (ethereal4k)

17- Elective mode (off by default). Gives MUCH more customization on where to stick your skills on your bar. (KroBa)

18 – Advanced tool tips (off by default). Shows advanced skill information such as % damage increase and what the skill does (KroBa)

19- While each player gets their own loot and gold drops, the health globes you pick up are shared and will heal other players if they are nearby. (Tolvinar)

22- Once you begin the fight with Jondar, use town portal and then wait in town for about 2 minutes. Once you go back through the portal Jondar will have summoned about 50 skeletons. They will most likely be in a tight group so you can get big massacre bonuses from this.( Tolvinar) That tip with Jondar will be great if they still have the achievement to kill 20 monsters in a single hit. I never managed that in the beta. (Oneironaut2)

23- Pressing "alt" will make items on the ground show their names for 10 seconds. The time can be adjusted in the options menu. (Tolvinar)

24- Instead of playing with your pinky on the shift key and the rest of your appendages on numbers 1-4 try this. switch the hold key from shift (default) to the spacebar. I felt it more comfortable if I played spacebar instead of shift. (spaceboundmonkeys)

25- Pressing 'Z' zooms in on your character until you press it again. (nathanstratton2010)

26- Checking the advanced tooltips option in the game play menus will show additional item information in your inventory while holding CTRL key. (snhender)

27- Numpad 0-9 will make your character say in game phrases (both audible and to chat). (kallell)

28- When hovering over a weapon in your inventory or a merchant it will bring up your currently equipped item to compare. However if you're dual wielding it will only bring up your primary hand. To quick view the other hand just hold alt. (dextini)

29- You must be level 10 to do hardcore. (kallell)

30– Your battletag is what is going to show up in game to your friends. As of now, character names really do not matter outside of the character select screen and in game dialog with NPCs. Pick a battletag that’s easily remembered and that you wouldn’t mind others seeing! (kallell)

31- Patch 1.0.1. bug - Running programs that put an overlay over Diablo III (such as Mumble, Xfire, and MSI Afterburner) can cause Diablo III to crash. Use these overlays at your own risk. (kallell)

32- Treasure goblins will disappear if they are not killed fast enough. Make sure once you see them they become a priority as they can drop vast amounts of gold and loot. (kallell)

33- Gems in game drop up to rank 8 now, ranks 9-14 need to be crafted. (kallell)

34– Magic find is averaged across group members. IE: if player a has 300 mf, and player B has 100, the MF rate for the group is 200. You get 20% of companion MF(kallell)

35- There is no “procs” for new recipes in crafting. All recipes become available on a rank by rank basis. (kallell)

36- Monster scaling (damage and HP) depends on the difficulty (norm, nightmare, hell, inferno) and players in game. Details can be seen here - http://goo.gl/BBKPU. (kallell) You WILL NOT get more exp per monsters the more players you have in the game. You do however, gain killing speed – theoretically farming monsters faster which in turn gives more exp and loot. (kallell)

37- If you fall behind or wander off away from your party, use your town portal and click their banner to quickly catch up.

38- MAKE SURE TO UPDATE GRAPHIC CARD DRIVERS (and sound card drivers if you have non-integrated ones)! This can have vast improvements on FPS. (kallell)

39- There will be two types of auction houses. RMAH and Gold AH. Gold sounds exactly like what it is. Sell and buy items off the AH with in game gold. With RMAH, you have two options. Send money straight to paypal or use “battle bucks”. If you choose to use battle bucks, the money will reside in your bnet account and can be used for other AH purchases, or blizzard merchandise. YOU CANNOT cash this out. If you intend on getting cash for items, be sure to go the paypal route.(kallell)

40- RMAH will not be available for the first week after launch. (kallell)

42- The official authenticator should be out today (May 14th) for 6.50 + S. However, you can always get the mobile app for free on any smartphone. (kallell) **Furthermore at the very least, make sure you sign up for mobile alerts. That way you get texted if anything is changed on your account (password, personal info, etc) Info and signup is here - http://tinyurl.com/7mu68rz (kallell)

43– Dual wielding gives 15% attack speed bonus. (riraito)

44- The best magic finding will be from killing rares around the world rather than simply boss farming (unlike d2). Every rare pack you kill, you gain a (stacking) Nephalem valor buff which increases your gold and magic find. Dying or switching runes removes this buff. Only kicks in after level 60(kallell)

45- You can re-assign the 1234 keys to QWER (good for MOBA players)(riraito)

46- Bosses have enrage timers. Inferno only?(kallell)

47- Press X to show hp bars of every individual monster (altzan)

48- Each vendor sells specific types of items that are generated when the game is created. If you want different items then remake the game.(riraito)

49- Unless they changed it from beta, magic (blue) items sold by vendors have unlimited stock. A cheap blue item can be a useful source of crafting materials if the auction house is too expensive.(tolana)

50- EXP chart basics:If the level difference is less than 5, there is no penaltyif the level difference is between 5-10, there is a small penalty (10%, 20%, 30%,...)If the level difference is more than 10, you'll only receive 5% experience (95% penalty)You only get "bonus" exp from monsters 6 levels below you. You gain increased (over 100% by default) exp by killing monsters up to 3 levels above you.

52- Activating 'Letterbox' mode in options will allow you to play in 16:10 if you have a 16:9 monitor. This means you will have more horizontal visibility. (Space-Dementia)

53- Not as much of a tip as just personal preference...Remap my skills to , W,.A, D and potion to Q and/or E.This way I can keep my hand in standard wasd position and have easy access to shift, alt, ctrl, skills and pots. No,need to reach for number keys.I usually put my "oh shit" skill on space bar since my first instinct near death is to press every button. (hsmith711)

54- If you fall behind or wander off away from your party, use your town portal and click their banner to quickly catch up.There are slash commands for the voice emotes (/followme /thanks etc). Voice emotes can be especially useful if you are playing with strangers who speak a different language.Unless they changed it from beta, magic (blue) items sold by vendors have unlimited stock. A cheap blue item can be a useful source of crafting materials if the auction house is too expensive.

55- Turn on the following features in game:

Elective skill mode.You can customize your action bar / hotkeys with your own order and select multiple spells from the same category ( i.e you could chose both teleport and frost nova as a Wizard or Firebats and Haunt as a Witch Doctor).

I wasn't aware of this until later on and I found the numerous, new build choices must more rewarding, so I was hoping to shed the light on something a few others might have other looked. (moobeat)
